Answer this question truthfully
### Question: When to seek urgent medical care when I have Basal cell carcinoma ?
### Response: If the biopsy shows that you have cancer, your doctor needs to know the extent (stage) of the disease. The stage is based on:
The size of the growth How deeply it has grown beneath the top layer of skin Whether it has spread to nearby lymph nodes or to other parts of the body
The stages of skin cancer range from Stage 0 (when the cancer involves only the top layer of skin) to Stage IV (when the cancer has spread to other parts of the body).
